Title: Suspension control device
Inventor: FUKATSU TSUNEHIKO
IPC: B60G17/015
Filed: 1984-06-13
Abstract: PURPOSE:To improve the comfortableness to drive a car and its operating stability by outputting running and road surface states from vertical oscillation acceleration, brake, and car speed signals in three steps and variably controlling damping force in a suspension for the car having damping force in three steps. CONSTITUTION:A vertical oscillation acceleration signal G is input to a logic circuit 7 through a low pass filter 4, a comparator 5, and a delay circuit 6 together with a brake signal B and a car speed signal V. These signals G, B, and V are independently processed by a NOT circuit 8, AND circuits 9 and 10, an XOR circuit 11, and a NOR circuit 12 and road surface and running states are determined and then hard H, normal N, or soft S signal is output according to the eight steps by the respective combination of states. In other words, when the vertical lower oscillation acceleration signal G is low, the N or H signal is output and when it is high, the S or N signal is output. As a result of this structure, the control that lays stress on the comfortability to drive a car or on its operating stability can be selected according to the road surface and running states.

Abstract: PURPOSE: To make it possible to apply a tension arm device to a magnetic tape device having a short rising time by carrying a short auxiliary tension arm so that the vluctuations during the rise and break of the tape may be absorbed by an auxiliary tension arm having a small inertia.  
     CONSTITUTION: A main tension arm 12 is coupled to a bearing 22 and is supplied with a tension from a spring 21. A rotational angle detector 23 is attached to the shaft of the arm 12, and an auxiliary tension arm 11 having a roller 10 is attached rotatably to the leading end of the arm 12 by means of a pin 25. There are provided stoppers 15 and 15' for regulating the rotational angle of the arm 11 together with a film-shaped mask 18 for detecting the rotational angle such that they are made movable between a light source 16 and an optical detector 17 which are attached to the main arm. The auxiliary arm is supplied with a tension from a stationary arm 13 and a spring 14. When a tape running speed is accelerated, the fluctuation in the tape tension are decreased by the rotations about a pin 25 because the inertia of the auxiliary arm 11 is small

IPC: B06B1/02
Filed: 1991-04-26
Abstract: PURPOSE: To generate a high frequency RF signal with enough amplitude and rise and decay speed for an envelope by forming an RF drive circuit of a driving means for an element which cuts and continues an electric current with the same amplitude corresponding to an peak amplitude of an electric voltage and a reactance constituting a resonance circuit connected with the element with a load by an RF connected with the load.

Abstract: PURPOSE:To prevent weld crack and to improve corrosion resistance and wear resistance at a high temp. by incorporating specific wt% each of C, Cr and V into a titled wire and further adding prescribed % each of W, Ti, Nb and Mo. thereto. CONSTITUTION:The composite wire is formed by incorporating 0.8-4.5% C, 0.5-2.0% Si, 0.3-2.2% Mn, 11-25% Cr and 2.0-15% V and further adding 1 or >=2 kinds among <=10% W, <=5.0% Mo, <=8.5% Ti and <=8.55 Nb thereto. A V-carbide is precipitated by increasing C and therefore the wear resistance and corrosion resistance are improved. The corrosion resistance and wear resistance of a build-up metal at a high temp. are improved by adding V at the ratio balance with the content of C and increase of Cr component. The components such as Ni, Ti and W contribute to the additional improvement of various characteristics at a high temp. and prevent the weld crack. The corrosion resistance and wear resistance are thereby improved and the weld crack is prevented.

Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To shorten the detection time and the interrupting time as compared with a conventional monitor by performing the monitoring through analysis or comparison of motor current or voltage of a driver. SOLUTION: An AC voltage obtained from a transformer 10, 12, 14 is rectified through a rectifier 16, 18, 20 and fed through a preresistor to each IGBT transistor constituting an electronic load relay where the AC voltage is applied between the gate and the emitter.

Abstract: PURPOSE: To provide the sound casting having less defects by substituting the atmosphere in a rotary mold with an inert gas atmosphere in performing centrifugal casting.  
     CONSTITUTION: Shutters 6, 7 are provided by leaving a spacing of about 15W30mm between the sand mold parts 2, 2' in both openings of a mold 1.

Filed: 1986-05-29
Abstract: PURPOSE:To obtain uniform orientation with a large tilt angle by applying high polymer resin over a substrate, lifting off this high polymer resin, and further performing a rubbing treatment. CONSTITUTION:A pattern 2 of <=1mum pitch is formed on a substrate 1 by using resist, the high polymer resin is applied over the surface of the substrate, and then a high polymer resin film 3 is formed by a heat treatment. Then, the resist is peeled off by using resist separating liquid and then the high polymer resin film is peeled off, thereby forming fine projections and recesses on the surface of the substrate. Then, the surface of the substrate is rubbed in a constant direction with cloth, etc., to grind the projections and recesses more on one-directional sides than on the other-directional dies, so the shape of the projections and recesses has directivity, but the shape and density of the projections and recesses are determined by the total pressure of the rubbing treatment and the pattern pitch. Consequently, liquid crystal molecules 4 are oriented stably in a constant direction at a pretilt angle theta.
